When asked if he's ever had any experience with changing diapers, he admitted, "Have I changed a nappy? I'd actually probably changed about a hundred nappies before Freddie because I used to help out with my sister so I have changed his nappy, thank you!"

He also revealed that he was "still getting used to" being away from his firstborn while on tour with One Direction, addeding "I miss him, obviously, but it's cool. I do get Father's Day now."

On the annual celebration of dads, Louis took to Instagram to share a shot of him holding Freddie's little hand.
